With ‘Lemminkäinen’ epic, Salonen and CSO capture Sibelius in youthful flower, prowess

Review: This is a perfect moment to reflect on Sibelius’ early mastery, in light of the great achievements by the twentysomething Schubert we’ve been hearing from the Chicago Symphony Orchestra and music director Riccardo Muti. And it is the fully flowered young Sibelius, before the First Symphony, caught up in the allure of Finnish myth and in absolute command of his symphonic craft, whom the CSO and conductor Esa-Pekka Salonen celebrate in a season-peak program heard April 3 and to be repeated April 8.
